When you perform an act of obedience, consider if you will, it's beginning, namely that it was by Allah's ability, power and gracious assistance. In this manner, may conceit be eliminated, and nothing remains but the acknowledgement of Allah's grace.
Or consider, if you will, its consequence, which is abundance reward and an excellent resting place. Thus will devotion increase and perseverance become a lighter burden. The first way of these two is more accomplished.
When you sin, beware of considering its beginning, which is pre-destination, that it may not lead you to raise objections to Allah, the Exalted, for that would be far worse than a sin. On the contrary, you should look at its consequence which is a painful chastisement and a severe torment. Thus will you hasten to repent and will increase in awe.
وَأَقِمِ ٱلصَّلَوٰةَ لِذِكْرِي
"And establish prayer for My remembrance."
